BankAccountSwitcher class

Bottom-sheet or inline widget for selecting among multiple bank accounts.

Typically presented as a modal bottom sheet via BankAccountSwitcher.show:

final selected = await BankAccountSwitcher.show(
  context,
  accounts: myAccounts,
  selectedAccountId: currentAccount.id,
);
if (selected != null) { /* switch to selected */ }

When embedded inline (e.g. inside an existing sheet), construct the widget directly and provide an onSelected callback.

Each row is 72 px tall and follows the 44×44 minimum tap-target rule. A drag handle is rendered at the top of the sheet for discoverability. Privacy mode is respected: balances are masked when BankUiScopeData.privacyEnabled is true.
